Report on a New Opioid NPS: Chemical and In Vitro Functional Characterization of a Structural Isomer of the MT-45 Derivative Diphenpipenol.

for the protonated molecule of m/z 389.2264, with two prominent fragment ions (m/z 91.0567 and 150.0937), which were not reported in earlier literature describing MT-45 derivatives. The chemical ...

Risk assessment of nitrate and nitrite in feed

nitrate in feed. For nitrate ion, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) identified a BMDL10  of 64 mg nitrate/kg body weight (bw) per day for adult cattle, based on methaemoglobin ...

Urinary sodium and iodine concentrations among Belgian adults: results from the first national Health Examination Survey.

and ion selective electrodes respectively. Tanaka and INTERSALT equations were used to predict 24-h urinary sodium excretion using sodium and creatinine concentration in spot samples, sex, and measured ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food

mass accuracy and retention times in a pesticide screening method that integrates all the features offered by coupling ultra‐performance liquid chromatography (UPLC) with ion mobility mass spectrometry ...

Estimating the Reliability of Low-Abundant Signals and Limited Replicate Measurements through MS2 Peak Area in SWATH

ions mass spectrometry (SWATH- MS) provides large-scale protein quantification with high accuracy and selectivity. Nevertheless, reliable quantification of low-abundant signals in complex samples remains ...

Survey on the Use of Whole-Genome Sequencing for Infectious Diseases Surveillance: Rapid Expansion of European National Capacities, 2015-2016.

funding, staff, and expertise. Illumina technology was the most frequently used followed by Ion Torrent technology. The access to bioinformatics expertise and competence for routine WGS data analysis was ...

Human absorption of silver ENM: through particles or ions?

Publication Type: Scientific poster, presentation or proceeding Authors: Nadia Waegeneers; A Brasseur; Van Der Heyden,S; Jan Mast; S. Roels Source: SETAC Brussels, SETAC, Brussel, België (2017) URL: https://brussels.setac.org/ Keywords: Absorption Nanopar ...

Clustering and diagnostic modelling of slimming aids based on chromatographic and mass spectrometric fingerprints

highly informative fingerprints. Three types of fingerprints were acquired (PDA, Total Ion Chromatograms (TIC), and MS fingerprints) which were used in the chemometric data analysis. Both unsupervised ...

Determination of total Ti in candy

spectral overlaps. Several collision/reaction gasses were tested using an Agilent 8800 ICP- MS- MS instrument. Solutions containing possible interfering ions (Ca, Cr, S, P, Cl or C) were injected to check if ...
